HAlR-PIN-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 594,844, dated December 7, 1897. Application filed September 10, 1896. Serial No. 605,448. (No model.) Patented in England December 12, 1894,1111. 24,13 5

T0 (ZZZ whom it may concern:

Be it known that 1, CHARLES BEAUMONT, a citizen of the United Kingdom of Great Britain and Ireland, residing at Roubaix, in the Department du Nord, France, have invented certain new and useful Improvements in Hair- Pin-Wlaking Machinery, (patented in Great Britain December 12, 1894, No. 24,134,) of which the following is a specification.

This invention relates to machinery employed in the production or manufacture of hair-pins and other similar articles having ball-points.

In the machine constructed for the purpose of this invention the wire is fed in lengths each of which is equal to the total length of the blank required for the production of the finished article. The wire having been fed is then held and cut. The blank thus formed is seized at the center and bent to the required form. The ends of the article are then seized and the ball or other similar points are formed by suitable punches. If the article is to be waved or otherwise further bent or shaped, this is accomplished while the article is still held for the formation of the points. The blank having thus been transformed into the completed article is released and falls into a receptacle below.

The accompanying drawings illustrate the apparatus by means of which this invention may be carried into effect and-are hereinafter referred to.

Figure 1 is a plan of the machine. Fig. 2 is a longitudinal section; Figs. 3, 4, and 5 represent details of the construction. Figs. 6 and 7 represent, respectively, an undulated and a plain hair-pin with ball-points such as may be produced by the machine.

A is the framing, and B the table, of the machine. The wire D is fed by the lever on,

' which by its oscillatory motion reciprocates the carrier at in the guiding-channels Ct". The carrier is adapted to seize and carry the wire in its forward stroke and to release it when moving back, as in other machines of a like character. The lever a is actuated by the cam 1. When the required length of wire has been fed, the lever 12 descends and holds the wire, this lever being actuated to operate at the proper time by the cam 2. Then the knife c,which slides in the vertical slides W,

knife is operated bythe cam 3 through'the lever a. At the same instant the wire blank is seized at the middle of its length bythe' end of the piece f and the former g actuated through the slide d by the cam 4. Then the jaws h, actuated through the slide 6 and plate e by the cam 5, move forward and bend the blank to the form of a hair-pin, while the con tinued motion of the piece f finally presents the points of the pin to the matrices p p, through the perforations q q of which they pass to such a distance that the points protrude on the opposite side. (See Figs. 1, 2, and 5-.)

The perforations of the matrices may be widened at the entrance to facilitate the en- 1 trance of the pin-points. The lower part 19' of the matrix is carried upon the verticallyreciprocating plate m, which is operated through the lever u by the cam 6. The upper part 19 of the matrix is fixed. As soon as the points have been inserted in the matrices the lower part 19 moves upward and the ends of the pin are thus seized and held while the ballpoints are formed by the punches Z Z, which are further illustrated in front elevation by Fig. 3. The punches are forced simultaneously against the ends of the blank to form the points by means of the lever j, the sliding rod 2', and the cam 7. Motion is preferably communicated from the lever j to the punches Z Z by means of the adjustable screws r r in the working direction. The punches, lever,

and slide-rod are respectively returned by the springs y 1/.

When it is desired to form an undulation in each limb of the pin, this is effected while the pin is still held in the matrices by the pressers n n and the stops t t, the two pressers simultaneously forcing the parts of the limbs between them between the stops, and thus producing the bend in each limb. The pressers are actuated by the arms 70 k, on each of which there is an inclined part. The arm 70 is moved by the action of the rod 2', on which there is fixed an inclined part is, which comes into contact with the inclined part of 7c, and thus moves it away from t. On the lever j there is an extension j, having a beveled end which operates in contact with the inclined part of the arm 70, and thus with the arms.

moves it simultaneously with the 'arm in. The arms 7s 7U" thus cause the simultaneous approach of the pressers, and the amount of their motion may be regulated by the adjust ing-screws, the heads of which form contacts The return of the pressers may be effected by means of the springs, as indicated by Fig. 1. The ball-points having thus been formed, the matrices open and the pin is withdrawn by the return motion of the former g and falls into a receiver placed below.

The described devices for producing the undulation in the limbs of the pin may be considerably modified, if used, according to results desired. As illustrated, the stops t t are fixed upon a removable bracket 0, Fig. 4, in the vertical member of which slots are formed for the passage of the fixing bolts 0r screws. More than two stops, with a corresponding increaseiin the number of presserpoints, may be employed if it be desired to produce more than a single undulationj Having nov particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In machines for making hair-pins the combination of a former, a seizing-piece for pressing the wire against the former, bendingjaws, a pair of matrices for holding the ends of the pins and pressers and stops for undulating the pins.

2. In machines for making hair-pins the combination of a former, a seizing piece, bending-jaws, a pair of matrices for holding the ends of the pins and parallel punches for forming ball-points.

3. In machines for making hair-pins, the combination and arrangement of the piece f and former g, the jaws h actuated by a cam 5, the matrices p p, and punches Z Z, all dooperating to bend and point the pins, substantially as set forth with reference to the accompanying drawings.

I. In machines for making hair-pins, the combination and arrangement of the piece f and former g, the jaws h actuated by a cam 5, the matrices p p, the punches Z Z, and the pressers and stops at n t t, all cooperating to bend, point and undulate the pins, substantially as set forth with reference to the accompanying drawings.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 30th day of July, 1896.

CHARLES BEAUMONT.
